If I ever get my car fixed up enough someone would want to steal it I plan on installing a kill device on the ECU along with a hidden GPS tracking device.
I have had a car stolen b4. Was lucky because they drove thru this small town around here known for its heavy police patrols. They left my plates on it and when
the cops rang it in it came up hot. They just pulled over and surrendered like bitches. When I got it back it was all there except you could tell that they tried to
steal my surplus navy battery that I had in it. I guess since it weighed almost 100 lbs they could not take it out lol.
